ABSTRACT

A bandwidth throttling method is provided. The method includes receiving by a receiver from a QD Vcel cannon, a plurality of multi-frequency light pulses via a plurality of channels. The receiver determines that the plurality of multi-frequency light pulses comprises an out of band (OOB) signal transmitted over a first channel of the plurality of channels. The receiver receives from a first laser device of the QD Vcel cannon, a first light pulse of the plurality of multi-frequency light pulses. The first light pulse includes a first frequency for testing a visibility of the first light pulse at the receiver. The receiver determines if the first light pulse is visible at the receiver.

FIELD

The present invention relates generally to a method for using multimodefiber optic capability to transport several frequency light pulses andin particular to a method and associated system for transport severalfrequency light pulses to achieve a maximum available band width for usein communications systems.

BACKGROUND

A fiber optics infrastructure typically requires an enormous datatransfer speed. The transfer speed may be increased to a higher levelenabling data transfer for transmission in a binary format usingmultimode fiber capacity to transfer data with respect to a higher baseformat such as like hexadecimal etc. to achieve higher transfer ratesusing a same fiber.

A typical fiber optics system may include tunable multimode laser diodemodules. A tunable multimode laser diode module may enable a method forcontrolling tunable multimode laser diodes, raman pumps, and ramanamplifiers. The aforementioned system may not be able to achieve higherdata transfer rates

An additional typical fiber optics system may include single cannonlight beams. A single cannon light beam only uses a single cannon fordata transfer thereby limiting data transfer rates.

Optical communications systems may achieve very high data ratesresulting from high bandwidth of optical fibers and the availability ofspecific high-speed laser systems. However a demand for increasing speedin communications may cause a typical optical fiber to be unable toprovide an unlimited bandwidth.

The aforementioned solutions may require the use of a specified type offiber optic cable thereby limiting the functionality of fiber opticcommunication systems. Additionally, the aforementioned solutions mayresult in an increase in the amount of noise introduced into the systemthereby reducing a quality of the transmitted signals.

Accordingly, there exists a need in the art to dynamically adjust tofailures in any frequency channel of a fiber optics system.

DETAILED DESCRIPTION

FIG. 1 illustrates a system 100 for transmitting multiple frequencylight pulses for enabling a maximum available bandwidth for use incommunications systems, in accordance with embodiments of the presentinvention. System 100 comprises (QD Vcel) laser cannons 102 a and 102 b(of a transmitter apparatus 126) transmitting the light signals to areceiver apparatus 114. Laser cannon 102 a comprises an out of band(OOB) single laser device. Laser cannon 102 b comprises a multiple lasercannon device. Front view 104 of laser canon 102 b illustrates multiplelaser crystals 104 a . . . 104 n for data transmission. System 100combines a set of frequencies 106 a and 106 b (generated by laser canons102 a and 102 b) together into a single (multimode) fiber cable 112. Thecombined set of frequencies represents patterns of bits 119 with respectto each light pulse.

Typical fiber optics systems include tunable multimode laser diodemodules to control tunable multimode laser diodes and a single cannonlight beam only using a single cannon for data transfer thereby limitingdata transfer rates. Additionally, fiber optics systems are typicallylimited to a single type of fiber optic cable to connect betweentransmitting and receiving devices. In contrast, system 100 usesmultimode fiber optic capability to transport several frequency lightpulses. Additionally, the use of a higher grade fiber comprising lowernoise ratios promote longer distance communications and therefore system100 is configured to adapt to the conditions of any fiber type and noiseintroduced into the system by external sources or by interference orattenuation within the fiber itself. Although the use of VCELS in atransmitter is not a requirement as any laser technology may be used togenerate a transmit cluster, system 100 enables the use of VCELS toprovide a maximum available bandwidth for use in communications systems.System 100 further utilizes preformed apertures to carry out of bandsignaling as well as multiple transmitter and receiver cluster grouptransmissions for transmitting and receiving using any type of fiber.Therefore system 100 enables transport a several frequency light pulsesover any type of fiber optic cable to achieve a maximum available bandwidth without introducing additional external noise into acommunications system.

Transmitter apparatus 126 and receiver apparatus 114 may each comprise aspecialized hardware device comprising specialized (non-generic)hardware and circuitry (i.e., specialized discrete non-generic analog,digital, and logic based circuitry) for executing a process describedwith respect to FIGS. 1-4. The specialized discrete non-generic analog,digital, and logic based circuitry may include proprietary speciallydesigned components (e.g., a specialized integrated circuit designed foronly implementing an automated process for transmitting multiplefrequency light pulses for enabling a maximum available bandwidth foruse in communications systems.

System 100 enables the use of a multimode fiber capacity by usingdiffering crystal sizes (i.e., for laser devices 104 a . . . 104 n) forlaser cannon 102 b to enable input of differing wave lengths into fibercable 112. A communications process is initiated when a transmitter 122enables an attenuation test by firing a laser beam with respect to eachof laser crystals 104 a . . . 104 n such that receiver device 114expects a receiver acknowledge signal for each of laser crystals 104 a .. . 104 n. The attenuation test is continuously run until anyunsuccessful transmitter crystals (of laser crystals 104 a . . . 104 n)are disabled. In response, a maximum number of concurrent signals fortransmission as well as a numeric base upon which data communicationwill occur are set. Additionally, a calibration phase is enabled. Thecalibration phase comprises transmitting a sequence of binary framesstarting from a highest number of active crystals down to one activecrystal and registering a definition for each color frame.

System 100 comprises a sender apparatus 126 and (laser) receiverapparatus 114. Sender apparatus comprises a light beam 123, transmitter122, and laser canons 102 a and 102 b. Receiver apparatus 114 comprisesa controller co-processor 114 a. Receiver apparatus 114 is enabled toreceive any light wave band color and determine (via co-processor 114 a)light wave color combinations that produced a resulting wave. Inresponse, co-processor 114 a caches a resulting bit pattern until thebit pattern fills a complete frame. The completed bit pattern is passedthrough processing with respect to higher level protocols. Theco-processor verifies a bit pattern checksum against received out ofband information, to ensure data was received properly or requiresre-transmission. If sender apparatus 126 comprises a legacy sender unit,system 100 will detect a light pattern and disable co-processor 114 afunctionality to conserve power. Sender apparatus 126 comprises amultiple QD Vcel array for emitting multiple channels or “colors”simultaneously as well as an out of band (IR or UV) laser emittingsignaling and checksum bits.

System 100 enables a process as follows:

Upon receiving an out of band signal, system 100 initiates a (bandwidththrottling) calibration process. If receiver apparatus 114 receiveslight pulses and no out of band signal is detected, system 100 enables alegacy mode, and disables throttling functionality. The calibrationprocess comprises enabling and disabling each of the Vcel lasers anddetermining a received color. Additionally, a series of all enabled/someenabled or all off Vcel laser pulses are processed to ensure that anaggregation of colors is being detected reliably. The calibrationprocess includes:

1. Receiving (by receiver apparatus 114 from QD Vcel cannon 106 a) agroup of multi-frequency light pulses via a plurality of channels.2. A co-processor determines that the group of multi-frequency lightpulses comprises an out of band (OOB) signal transmitted over a firstchannel of the plurality of channels.3. Receiver apparatus 114 received (from a first laser device of QD Vcelcannon) a first light pulse of the plurality of multi-frequency lightpulses. The first light pulse includes a first frequency for testing avisibility of the first light pulse at receiver apparatus 114.4. The co-processor determines (in response to receiving the first lightpulse) if the first light pulse is visible at receiver apparatus 114. Ifthe first light pulse is visible at receiver apparatus 114 then alllaser devices are independently tested and differing groups of thelasers are tested within a specified threshold until the calibrationprocess has completed. If the first light pulse is not visible atreceiver apparatus 114 then the laser device is disabled and additionallaser devices are tested until the calibration process has completed.

Upon completion of the calibration process, co-processor 114 adetermines a base at which the data transmission will be throttled,(1x-“n”x) and a (bandwidth throttling) communication process isinitiated. If an error detection of more than an acceptable amount ofpackets is determined then, the calibration process will re-start toeliminate unreliable channels. The communication process includes:

1. Assigning (by the computer co-processor) bit locations for aplurality of multi-frequency light pulses transmitted over a pluralityof channels enabled by the lasers of the QD Vcel cannon. The assignmentis based on a laser pattern table (generated during the calibrationprocess) describing laser generated light pulses.2. The co-processor appends a parity bit associated with the OOB signaltransmitted over a first channel of the plurality of channels.3. An odd or even number of frequencies of the plurality ofmulti-frequency light pulses are compared with the parity bit.4. It is determined (based on results of the comparison) if a patternassociated with the plurality of multi-frequency light pulses comprisesa correct pattern. If the pattern is correct then bit locations for anadditional plurality of multi-frequency light pulses transmitted over anadditional plurality of channels enabled by the lasers of the QD Vcelcannon are assigned based on the laser pattern table. If the pattern isnot correct then plurality of multi-frequency light pulses arere-transmitted over the plurality of channels to determine a correctpattern.

FIG. 2 illustrates a flowchart detailing an overall process enabled bysystem 100 of FIG. 1 for transmitting multiple frequency light pulsesfor enabling a maximum available bandwidth for use in communicationssystems, in accordance with embodiments of the present invention. Eachof the steps in the algorithm of FIG. 2 may be enabled and executed inany order by a computer processor executing specialized computer code.In step 201, the process is initiated. In step 204, a receiver apparatus(e.g., receiver apparatus 114 of FIG. 1) receives (from a QD Vcel cannonof a transmitter apparatus) a plurality of multi-frequency light pulsesvia a plurality of channels. In step 208, a (computer) co-processor ofthe receiver apparatus checks for an OOB signal. If in step 210, theco-processor determines that the plurality of multi-frequency lightpulses comprises an OOB, then step 302 of FIG. 3 is executed asdescribed with respect to FIG. 3, infra. If in step 210, theco-processor determines that the plurality of multi-frequency lightpulses does not comprise an OOB, then in step 212, a legacycommunication mode is enabled. In step 214, communications aretransmitted and step 402 of FIG. 3 is executed as described with respectto FIG. 4, infra. The process is terminated in step 216.

FIG. 3 illustrates a flowchart detailing a calibration process enabledby system 100 of FIG. 1 for transmitting multiple frequency light pulsesfor enabling a maximum available bandwidth for use in communicationssystems, in accordance with embodiments of the present invention. Eachof the steps in the algorithm of FIG. 3 may be enabled and executed inany order by a computer processor executing specialized computer code.In step 302, a signal is transmitted from a transmitter device over anOOB channel. In step 304, the transmitter device determines a nextindividual frequency light pulse (e.g., light pulse or color) to betransmitted. In step 308, next individual frequency light pulse (i.e.,that has not been tested) is transmitted to a receiver apparatus. Instep 310, the receiver apparatus tests the received individual frequencylight pulse for reliability. In step 312, it is determined if thereceived individual frequency light pulse is reliable (i.e., visible).If in step 312, it is determined that the received individual frequencylight pulse is not reliable then in step 318 the transmitter apparatusdisables the associated QD Vcel laser transmitting the receivedindividual frequency light pulse and step 304 is repeated to determineanother individual frequency light pulse for transmission. If in step312, it is determined that the received individual frequency light pulseis reliable then in step 314, it is determined if all individual laseremitters have been tested. If in step 314, it is determined that allindividual laser emitters have not been tested then step 304 isrepeated. If in step 314, it is determined that all individual laseremitters have been tested then in step 320, it is determined if thereceived individual frequency light pulse is unreliable. If in step 320,it is determined that the received individual frequency light pulse isunreliable then in step 324, the transmitter apparatus disables anassociated Vcel laser and step 322 in executed as described, infra. Ifin step 320, it is determined that the received individual frequencylight pulse is not unreliable then in step 322, the transmitterapparatus determines a group of multiple frequency light pulses fortransmission. In step 326, it is determined if the testing process hascompleted. If the testing process has completed then step 214 of FIG. 2is executed as described, supra. If the testing process has notcompleted then in step 328, the transmitter apparatus transmits a nextgroup of multiple frequency light pulses (that have not been tested) fortransmission. In step 330, the receiver tests the next group of multiplefrequency light pulses for reliability and in step 332 it is determinedif the received (i.e., from step 328) group of multiple frequency lightpulses is reliable. If the received group of multiple frequency lightpulses is reliable then step 320 is repeated. If the received group ofmultiple frequency light pulses are not reliable then in step 334 it isdetermined if a testing retry threshold has been reached. If the retrythreshold has been reached then step 320 is repeated. If the retrythreshold has not been reached then in step 338, a request for thetransmitter apparatus to retry a last frequency light pulse combinationis enabled and step 328 is repeated.

FIG. 4 illustrates a flowchart detailing a communication process enabledby system 100 of FIG. 1 for transmitting multiple frequency light pulsesfor enabling a maximum available bandwidth for use in communicationssystems, in accordance with embodiments of the present invention. Eachof the steps in the algorithm of FIG. 4 may be enabled and executed inany order by a computer processor executing specialized computer code.In step 402, a bit location is assigned to enabled lasers (e.g., oflaser devices 104 a . . . 104 n of laser cannon 102 b of FIG. 1) basedon a laser pattern table describing laser generated light pulses definedduring the calibration process described with respect to FIG. 3. In step404, a parity bit is calculated for an OOB channel. In step 408, enabledlasers for a QD Vcel laser and associated OOB are triggered for alogical high bit. In step 410, the receiver apparatus tests a receivedsignal with respect to the parity bit. In step, 412, it is determined ifthe bit pattern is reliably received. If the bit pattern is reliablyreceived then step 402 is repeated. If the bit pattern is not reliablyreceived then in step 414, it is determined if a maximum number of bitpattern receiving tries has been reached. If it is determined that amaximum number of bit pattern receiving tries has been reached then step302 is repeated. If it is determined that a maximum number of bitpattern receiving tries has been reached then in step 418, aretransmission for the bit pattern is requested and step 404 isrepeated.
